VALVE.

Application filed'March 8, 1924. Serial No. 697,815.

To all whom it may concern:

' Be it 'knownthat I, HOWARD S. COREY, a

citizen of theU nited States, and resident of MunhalL-in the county of Alleghenyand State of Pennsylvania, have invented certa-in new and useful Improvements in Valves, of which the following is a specification. r

This invention relates to valves, and while not limitedthereto relates more particularly to valves primarily adapted for use as re- =versing valves in regenerative furnaces and 1 the like.

@ne object of the presentinvention is to provide a valve of this type that will maintain substantially seated. 1

perfect sealing when Another object is to provide a valve which may be mounted in the fines leading from "the-regenerative chambers so as. to control flow through said fines and thus eliminate the necessity of usingslide dampers.

A further object is to provide a reversing valve 'which is composed of few parts, only one of which is movable, thereby reducing wear to ai -minimum.

A still furtherobject is to provide a valve composedof the novel combination, arrange ment, andcombination of parts hereinafter described and illustrated in the accompanying drawings. I

In the drawings, Flgure 1 1S atop plan showingthe regenerative chambers, stack and connecting flues of a standard form of regenerative furnace.

Figure 2 is a sectionalelevation on the "line I I- 110f Figure 51.

ings, the numerals 2 and 2 designate the I regenerative chambers of standard construction, wh ch are connected-by lines 3 and 4,

respectively with the stack 5.

The flues'3 and 4: are each provided with --the novel reversing valve of my invention,

designated as a whole by the letter A.

The 'va lve is composed of upper and lower seat members 6 and 7 respectively, the lower-seat member being provided with a passageway7 forthe circulation of a cooling medium; 'Theupper seat member6 is 'arrangedon a horizontalplane in a suitable regenerative chambers.

The seat members 6 and 7 are provided with projections 9 and 10, respectively, at"

one point in their circumference, which form connecting lugs and are detachably secured together bybolts 11 or the like.

The lower seat member 7 projects downwardly from the upper seat member 6 on an angle of approximately 45 degrees and is mounted an a suitable inwardly projecting rim or shoulder 12 formed in the flue.

The seat members 6 and 7 are provided with depressions 14L and 15, respectively, in their lugs 9 and 10, respectively, which cooperate to form a spherical socket.

A flap valve 16 is mounted to seat on either, of the seat members 6 or 7, and comprises a disk body portion having a projecting ball connection 17 adapted to be mounted in the socket formed by depressions 7 1i and 15, so as to form a universal pivotal connection. I I

The body portion of-the valve 16 has both its upper and lower edge beveled as at19 and 20, respectviely, to form a-tight seal with the beveled faces 21 and 22 of the seat members 6 and 7, respectively.

The ball and socket mounting for the valve 16 permits a universal movement of -the valve and thus insures'perfect seating thereof.

A suitable mushroom valve 23 is suspended over the inlet conduit formed by the rim 8. on the upper seat 6, and is adapted'to regulate the inflow of air through the inlet. The mushroom valve 23 is suspended from suitable chains 24 which 'passaround sheaves 25 on a shaft 26 mounted in a sup porting frame 27 secured to an overhead beam 28 or the like. The chains 24. are provided with counterweights 29 to counterbalance'the valve 23. The shaft 26 is-pro- 'vided with asheave 30 which is connected by a chain 31 to a sheave 32 on a power shaft 33 mounted 111 a stand 34 and adapted to be rotated by a'crank 35. The valve 23 is only raised and lowered occasionally to regulate the inflow of air and the hand operation is,therefore, sufficient, although a suitable power means for moving the valve maybe provided if desired.

Thevalve 16 is provided on its upper face with a centrally arranged guide bracket 3b having an upstanding curved guide arm 36 which is curved upwardly and rearwardly toward the hinged or pivotal connection of the valve.

A suitable lifting chain 36 has its one end connected to the center of the bracket 36 in line with the center of the valve. The chain 36 is trained upwardly through a centrally disposed opening 37 in the valve 23 and thence over a sheave 38 mounted on a shaft 39 in the frame 27, and has its other end secured to a hydraulic cylinder 40. A suitable coiled spring 41 is shown between the two sections of the chain 36 for the purpose of smooth working, without jar or shock when operating the valve. The curved guide arm 36 serves to maintain the lifting chain 36 centrally within the opening 37, thus permitting operation either of the valves 23 or 16 without interference with the other.

In operation the flap valve 16 on one side of the stack will be raised to seal against the seat 6 and the valve 16 on the other side of the stack will be lowered to seal against the seat 7 when it is desired to reverse the furnace, and due to the universal pivotal mounting of the valve 16 a perfect seal will be made with either the upper or lower seats.

lVhile I have illustrated my valve as applied to a regenerative furnace requiring regeneration of air only, it will be understood that my valve may be applied equally as well to furnaces requiring the regenera tion of both air and gas by the simple addition of another set of valves.
